Currently, CNC technology is increasingly popular in Vietnam and accounts for about 70% – 80% in the field of high-tech mechanical processing. CNC machines have been introduced to Vietnam since about 20-25 years ago, so the old CNC machines are occupied by a large number of factories and enterprises. In order for CNC machines to be available, stable and long-term operation, we need to maintain and maintain machines periodically.
When the machine has been damaged, needs to be replaced or restored, some machine functions are improved, we offer an upgrade solution.
With many years of experience in the field of maintenance and maintenance of machine tools and with a team of engineers trained at home and abroad, we offer a service to upgrade CNC machines to ensure contentment. Best regards to customers.
When to apply upgrade solution for CNC machines?
When the mechanical part of the CNC machine is good, the mechanical deviation of the axes is within the permitted range but the machine has the following problems or problems:
– When the power system – control is badly damaged, it cannot be overcome.
– When customers want to replace the current control system by a new control system, meeting the actual production technology requirements of the factory.
Advantages of choosing a machine upgrade solution:
Keep and optimize the good frame.
Costs will be much lower than investing in new machines with the same control system.
The upgrade machine has a new control system with technology and optimization updated at the time.
– The ability to interpolate smartly and accurately.
– Ability to calculate and preview large processing scripts.
– Ability to communicate easily data. Large internal memory.
– Strong simulation ability.
field of application:
– Types of milling and turning machines from 2 axes or more.
– Types of CNC cutting machines: wire cutting, pulse, Plasma, water jet, …
– Other machine tools: Grinder, boring, drilling, punching, bending, …
– Common universal machines, NC machines have full parameters, ability to upgrade to CNC machines.
CNC upgrade process
SURVEY:
Surveying is an important first step in upgrading CNC machines. In order to assess the current state of the machine, it is the basic for solutions for the most reasonable upgrade of function, stability, accuracy and cost.
CHOOSE SOLUTION:
Controller, motor, inverter
Currently, there are many control systems in the world for CNC machines such as SIEMENS, FANUC, HEIDENHAIN, MITSUBISHI, FAGOR, OKUMA, GSK, CENTROID … Therefore, it is necessary to select a control system for fitting With technology, easy to use and installation.
For factories in Vietnam, the selection of control system and electrical systems of SIEMEMS, FANUC, GSK and CENTROID used for upgrading will ensure the requirements of technology, price and friendly, easy to use. .
The type of control system will give us the choice of the type of motor, the corresponding inverter.
Auxiliary system:
Check the functions of the machine to create a recovery solution or add the auxiliary device to help work with the full capacity and highest stability:
Construction of electricity system:
After selecting the control system and auxiliary systems, we have to build the electrical system diagram for the machine. Calculation of capacity, load capacity and stability, …
